I like your top five list. I agree that the e30 isn't the greatest looking car. I do like the e36, just not when its "slammed" or when you can't see all of the tires. I don't get the whole fad with that (Sorry Pat
. Your car looks good low though)
Slammed and stretched is the only way... For me atleast... I like my cars like I like my girls.
HOW MUCH DO YOU HAVE TO SPEND ON THE CAR? AND WHEN WILL YOU, IF YOU DO MOD THE CAR. This is the most important thing.
Have you ever thought of a sc300 or a sc400??? Most of them are auto BUT the swap to 5spd is under 1k. the 2jz non turbo isn't a bad motor and the 1uzfe is pretty sick too. These cars are much nicer then a 240sx and an e36 and Cost about the same.
When you say 240sx do you mean s13 or s14? A stock s13 SUCKS!
You will need coilovers, wheels, suspension arms, and atleast a ka24de (still dead slow) before you will even want to touch the car.
AN S13 BLACK TOP (DO NOT GET A RED TOP Water ports in head fail, reversing water flow at times wise words from when I met Taka Aono when I met him) SR20det swap is about... $1700 Shipped (they did Ben's for 1600 shipped)

To install you will need to know how to wire about 8 or 10 wires I think.
A walbro 255 $90
and an exhaust system although you could reuse the stocker. $150-1000.
Intercooler setup- $100-500
Aside from that just random things to install like bolts, motormounts if the stocks are bad, wire ties, etc (about $100-$300)
So this swap is going to run you about $2200-4lk depending on who you have help you and what you do... Like I said my friend Ben has done a few and would help you out on it (it really is a simple swap). You should take a ride in his drift car to see if it is something you even want to start with.
My e36 was slow, I chipped it and it was still slow. It was one of the best handling cars I have ever been in tho... mine was seam welded and braced in all of the weak points. THERE ARE a lot OF e36 issues that you dont know about. READ!
The issues with an e36 might be too much for you as a nice one with no issues is going to cost more then an s13 with a sr20 swap already done.
For the money the FASTEST would be to build a 240sx with an sr20det... swap is simple (I have sat thru 4 of them). It takes a few hours to do.
The most important thing is for you to find a few... test drive them. Find stock ones and then ones that have what you would want. Only real way to tell what you want. We can tell you oh get this and that but in the end it is up to you!
